This book was a waste of my money and time. I was looking for a thorough exposition of the relevant, important, and historic differences between denominations; Dr. Rhodes does a poor job of giving this to the reader. I know this because of the denominations I am very closely associated with (or have been associate with), he does a poor job of getting to the important and essential real differences of which I am very familiar. This book was so poorly done that I threw it away in great frustration and disappointment (especially compared to the great work he has done on the cults). DON"T BUY IT!!
